I started vaping about a year ago and have never been able to build a decent set of coils. Until now. I picked up the boom boom coil rig and holy ..... First build was a perfect dual coil .4 ohms setup. Then I thought hmm, what if I twist some kanthal. 26ga twisted with 7 wraps per coil. .14 ohms of juice chucking awesome! This coil rig is amazing. If you want perfect coils every time in half the time, seriously pick this up.
